Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom appliances, in particular to a urinal. BACKGROUND

[0002] In the prior art, the lower part of the urinal bowl is designed to include a sewage discharge section, which is usually in the shape of a vertical downward channel, and is connected to a sewage pipe to realize wall discharge or ground discharge. The upper end of the sewage discharge section is designed with a step for installing a ceramic or metal plug for filtration, and the aperture of the sewage inlet is relatively small. The sewage discharge section with a plug design is prone to splashing water problems. During use, when the flushing water flow and urine directly impact the ceramic or metal surface, a large reaction force is generated due to the collision of the water flow with the hard surface, causing the liquid to be ejected far away. This design makes cleaning and maintenance complicated, and dirt is easy to accumulate and difficult to completely remove. The small aperture of the plug has a certain filtering effect, but it also slows down the urine flow rate and increases the risk of blockage, thereby affecting the drainage efficiency. SUMMARY

[0003] The utility model aims at at least in a certain extent solves one of the foregoing technical problems in the related art. To this end, the utility model provides a urinal.

[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0005] According to the urinal of the utility model embodiment, the sewage discharge section is connected to the sewage inlet section, the sewage discharge section is connected to the sewage inlet section, the sewage inlet section forms a water seal area, the front wall of the sewage inlet section is inclined from top to bottom and rearward, the upper part of the front wall is a convex arc surface, the lower part of the front wall is a concave arc surface, forming an inclined wall surface with convex upper part and concave lower part, the convex arc surface and the concave arc surface are smoothly connected, the upper end of the convex arc surface is smoothly connected to the front wall of the urinal bowl, the lower end of the concave arc surface is smoothly connected to the sewage discharge section, the virtual connecting line L from the upper end of the convex arc surface to the lower end of the concave arc surface has an angle β with the horizontal plane, the angle α of the left and right side walls and the rear wall of the sewage inlet section with the horizontal plane is greater than or equal to 75 degrees.

[0006] According to the urinal of the utility model embodiment, at least the following beneficial effects are achieved:

[0007] The urinal of the present application adds a pollution inlet section, adopts a smooth design, and has a funnel shape as a whole. When used in combination with a pollution discharge pipe, the pollution inlet section can form a water seal area. Compared with the ceramic or metal partition used in the pollution discharge section in the prior art, this design can effectively reduce the impact force and rebound force of the water seal surface when the urine hits, thereby effectively preventing urine splashing and pollution and reducing the risk of hygiene. The water stored in the pollution inlet section can also inhibit the upward flow of odor, ensuring the long-term deodorizing effect. In addition, the front wall of the pollution inlet section is designed as a smooth inclined curved surface, which is relatively gentle, while the side wall and the rear wall of the pollution inlet section are designed to be steeper. This design can effectively control the speed and direction of the water flow. The gentle structure of the front wall of the pollution inlet section reduces the resistance when the pollutants enter, ensuring that the water flow can flow smoothly into the pollution discharge section. On the contrary, the steep design of the side wall and the rear wall of the pollution inlet section can quickly guide the water flow directly to the pollution discharge section, avoiding the water staying inside for too long. This structure not only improves the flushing efficiency, but also reduces the formation of internal vortex, thereby reducing splashing and noise. The steep structure of the side wall and the rear wall of the pollution inlet section also enhances the kinetic energy of the water flow, ensuring a more thorough flushing effect and further improving the cleanliness of the urinal.

[0027] In use, urine and flushing water flow into the bowl 100 and converge in the inlet section 300, and the splashing caused by the water flow impacting the water surface of the water seal area is relatively gentle, and the distance and quantity of liquid splashing are reduced, thereby giving the urinal excellent splash-proof characteristics, effectively reducing the inconvenience and pollution risk in use.

[0028] In some embodiments of the utility model, 30°≤β≤45°. β represents the overall inclination of the front wall 310 of the inlet section 300, and controlling β to be 30°-45° can obtain a relatively gentle and smooth curved surface, effectively controlling the speed and direction of the water flow.
